When this work is accomplished, the tender is instructed by telephone to begin the pumping out of the pontoons, and the motor in each is started by the electrical-power generator in the ship. The men in the bell can observe the operation from a little distance, and send up instructions to pump out certain pontoons more rapidly than others, in order to bring the wreck right side up. As the water is emptied from these cylinders, they become more and more buoyant, until they strain at their chains, tug at the vessel, and finally raise it from the mud and bring it to the surface, where the tender ship can tow it to the nearest port for the recovery of its contents, or, if the vessel is not beyond repair, for overhauling and restoring to seaworthy condition. In many cases the recovery of the ship alone would be worth the expense, while in others the treasure is immensely valuable. The location of scores of wrecks is no secret, but the methods of raising the sunken vessels has made the knowledge worthless. The Los Angeles man who has perfected this unique diving bell believes that he has solved the problem. Our Flag Again on the High Seas. A few days ago the _John Ena_, a big four-masted bark, sailed majestically through the Narrows into the lower bay at New York City. Recalling as it did the days when the lofty rigging of American ships dominated the sky line along the water front instead of the tall buildings which are now to be seen there, the arrival of the _John Ena_ was the first striking evidence to shipping men of the return of the United States flag on the high seas. Since the new registration regulations went into effect, the rehabilitation of the merchant marine has made itself known practically every day in the arrival or departure of some steam vessel which had been changed to American registry, but the presence in the bay of an American-owned and American-manned sailing vessel of the type of the _John Ena_ was the most eloquent reminder of all to those who could remember the old days. The _John Ena_ came from Honolulu, Hawaii, with a cargo of raw sugar. The records show that between September 1st and November 15th, eighty-four ships came under the United States flag through the new law, which extends American registry to foreign-built vessels. This was more tonnage than had been added to the American merchant marine in the previous twenty-five years. The American merchant marine now consists of 2,444 ships of 1,369,492 gross tons. Of the eighty-four ships, seventy were British, eight German, five Belgian, and one Norwegian, disproving the contention raised when the legislation was pending that it was merely a scheme to make available and protect with a neutral flag the German ships tied up idle in American ports on account of the war. Practically all of the ships were American owned, flying alien flags merely because their owners built them abroad, where cost of construction and operation was low.
